Specification of Letters IEatent. Igatenfied 31 24 1 916 Application filed July 26, 1915. .Serial No. 41,856.

To all whomz't may concern Beit known that I, EowAnoP. CAnLsoN, citizen of the United States, residing at Seattle, in the county of King and State of \Vashington, have invented a certain new and useful Improvement in Valves, of which the following is a specification.

My invention,relatesto improvements in valves for; controlling the How of fluid through conduit pipes, and the object of my in'iprovement is to provide a valve whose passageway may be opened by a manual actuation of-sorne of the operative parts and be closed automatically by other of its operative parts in response to, the action of the fluid to which such other parts are subjected, orywhose said passageway, after being so opened may bemaintained, open, if it be so desired,;bythe manual adjustment of another of; its parts; and afurther object of my improvement is to provide a valve whose movable parts may be actuated without the aid of any spring and which shall be durable and ,reliablyeiiicient in itsoperation. I accomplish this objectby devices illustrated in the accompanying drawings wherein I have shown my invention as embodied in a faucet which isadapted for use in connection with water supply pipes associated with stationary wash-basins, wash-tubs, bath-tubs and the like, and in which drawings- Figure l is aview of such faucet showing itsprincipahparts in vertical mid-section; Fig.2 is, a view oiltheisame inhorizontal section on broken line a, a; of Fig.,1; l3ig.3 is a view otthe -same in,horizontal section on broken; line 1 y of -Fig 1 and,Fig. d is ga -fragmentary viewof, the same on broken line s, aof Fig.1; V

ihef r ng t th dr w r hrough ut wh ch like reference numerals lnd cate llke parts,tubular base portion 5 is provided with -a,.downward ly extended nipple ;6,,by whichthe faucet maybe secured to a support an d c nnected to a water supply pipe, and is further provided with an external screw-thread around its upper end portion,

;wl 1ile,the inner side of ;its,circular wall is provided with a ,plurality of vertical grooves 7 Within the tubular base portion 5 is loosely disposed a cylindrically formed hollow metal float 8 whose buoyancy adapts it to rise to its position shown in Fig. 1 in response to the presence oi water in said base portion 55,- which "water :may find passage waysithrough said grooves 7 to the space ahovesaidfloat 8. Screwed onto the screwthreaded upper end portionof said base portion 5 is the internally screw-threaded flange 9 of ,a hollow metal body portionlLO whose bottom; wall 11 is provided with a concentrically disposed passageway that extends upwardly throughit and througha sleeve 12 which isintegral therewith, said passagewaybeing countersunk in its lower end to provides seatfor a puppet valvelid removably disposed therein, said puppet valve13 being integrally attached to a valve spindle 14; which extends upwardly through the sleeved? into thespacethereabove.

,The valve-spindle leis provided with a plurality of grooves 15 (as shown more clearly in Fig. 4) which extend fromthe puppet valved?) to its top end whereby water may flow upwardlythrough the sleeve 12 ifthe pnppet valve 13 bemoved downwardly i i-omits seat in response to pressure exerted on the top end of the valve-spindle 141-.

Extending ,downwardlyfrom the bottom of the puppet valve 13 is a boss 16 against the bottom end of which the top side of the float 8 engages to exert a pressure that tends to alnaintain said puppet valve 13 in its closed position. 1

lhe top wall of the-body portion LOis providedwith a concentrically (disposed hole that extends upwardlyithrough it and the side surface of said hole atap'oint nearits bottom end is provided with a circumferential groove li, and such hole is further pro vided with a. slot l8 that extends vertically throughout itsllength, and within said hole is slidably disposed aiplunger 19 whose bottorn endsuriace is engaged by the end surface of the valverspindlela.

.The plunger 19 extends upwardlyfor a distance above thetop of the; body portion 10 toaiengage with a lever 2,0,,one endof e sponse to a rotary movement of said plunger 19 when said plunger 19 is depressed to move said pin 23 downwardly to a point where it registers with said circumferential slot 17, thus to lock said plunger 19 in such position that the puppet valve 13 will be "opened'to permit water to pass upwardly through the grooves formed in the valvesteml l; and such rotary movement of said plunger'19 may be effected by turning a .milled nut 24 fixed on the upper end of said plunger 19.

" The top of th'ebody portion 10 is provided with an upwardly projecting screwthreaded flange 25upon whichis disposed a screw-threaded flanged collar 26 which serves to confine a'suitable packing that ,may engage with the circumferential surbody 'portion'lO.

face ofthe plunger 19 to prevent a leakage of water from'theinterior space within the 3A curved nozzle 27 is screwed into a screw-threaded holedisposed in the side wall of the body portion'lO to extend therethrough thus to permit water to escape from the interior space of said body portion 10.

The operation of the faucet, thus illustrated and described is as follows: The

: nipple 6 being attached to a water supply pipe, in a well known manner, water will enter the space within the'base portion 5 withjthe result that the float 8, by its buoy- V ancy, will raise the valve-spindle 1 1 to 7 cause the puppet valve 13 to-close the passageway through the sleeve 12 and the groove 15 and'to cause the plunger 19 to rise and lift the lever 20 to its normal position, as indicated in Fig. 1, the force of such buoyancy of the float 8 being aided by the impact or pressure of such water, and after the puppet valve 13 is thus closed, then the buoyancy of the float 8 alone will be suflicient to maintain the puppet valve 13 puppet valve 13 automatically to actuate the puppet valve 13 to move upwardly to close the passageway through the sleeve 12 7 copies of this patent maybe obtained for and the grooves-l5. If, however, it be desired to lock the puppet valve 13 in its wide open position to permit water from the nozzle 27 to flow continuously, then in such case, :when the plunger 19 has been depressedto thatposition. where the pin 23 registers with the circumferential slot 17,

the milled nut 21 is turned to rotatively move said plunger 19 to cause said pin 23 to enter the circumferential slot 17 thus to prevent an upward movement of said plunger 19, in a well known manner. After water has flowed continuously through the nozzle 27 for a required length of time then the milled nut 24 is turned to rotatively move the plunger 19 until the pin 23 registers with the vertical slot 18 whereuponthe plunger 19 will be permitted to rise in response to pressure exerted through the valve-spindle 14:.

If it be desired, the pin 23 in the plunger 19 and the'vertical slot 18, together with the circumferential slot 17 may be dispensed with, in which case, the said plunger 19 cannot be locked in a position to maintain the puppet valve 13 open.

Manifestly, changes may be made in the forms, dimensions and arrangement of parts of my invention without departing from the spirit thereof.

hat I claim is:

In a valve of the class described the combination with a tubular member having an enlarged chamber at its upper end and having its lower end portion adapted to be attached to a fluid-supply pipe, the enlarged chamber being provided with longitudinal. channels in its walls, of a buoyant member fitted within said enlarged chamber with the periphery thereof engaging the inside wall of the enlarged chamber and slidable therein, the said channels forming passages disposed in spaced relation around the buoyant member, a hollow body member having a hole through its top wall and dis posed with its bottom wall covering the top end of said tubular member and secured thereto, said bottom wall having an upstanding nipple with a passageway extending upwardly therethrough; a puppet valve carrying an integral depending lug disposed to engage with said buoyant member and adapted to open and close said passageway in response to its vertical movements; :1

plunger disposed to be slidably movable within said hole in said top wall of said body member and adapted to engage with said puppet valve whereby said puppet valve may be disposed to open said passageway in response to a downward movement of said plunger; and a delivery pipe disposed to conduct fluid from the space within said body member.

In witness whereof, I hereunto subscribe my name this sixth day of July, A. D.
